<p>Roots are morphologically and physiologically complex and known to provide multiple purposes, such as anchorage, nutrition, and water supply, and the synthesis of exudates with growth-promoting and regulating qualities. The root-soil interface, known as the rhizosphere, is considered the most biologically active part of the soil. The interactions occurring at this interface are highly complex and mediated by root exudates secreted by the plant roots in significant amounts into the soil rhizosphere through live root hairs or fibrous root systems. Root secreted metabolites are engaged in a number of activities in the rhizosphere. Plants may influence soil characteristics by modifying the constituents of root exudates, allowing them to adapt and survive under harsh environments. They employ a variety of techniques, including modifying the hydrogen ion concentration of soil that helps in nutrient and mineral solubilization, chelating toxic compounds, interacting with beneficial microbes, and secreting toxic substances for their protection. Therefore, root exudates affect the entire plant by shaping the rhizosphere, enhancing stress tolerance, promoting plant growth, advantageous symbioses, nutrient uptake, and water uptake. In this review study, we discuss the composition of root exudates, factors affecting root exudates, distinct mechanisms of root exudation in the rhizosphere, and their impact on plant health and nutrition.</p>
